HTP 64980308 High Limit Aquastat Control for SuperStor Indirect Water Heaters

The HTP 64980308 is a Honeywell L4080B-1352 high limit aquastat controller designed specifically for use with HTP SuperStor and Contender indirect water heaters. This immersion-type temperature control device provides reliable safety protection by automatically shutting off the burner when water temperature reaches the set point, preventing scalding and system damage.

Key Features:

• Temperature range: 100°F to 200°F with adjustable set point
• Fixed 8°F differential for consistent temperature control
• Liquid-filled sensing element expands as temperature rises
• Diaphragm-actuated snap switch provides reliable operation
• Factory-set stop prevents setting control at excessive temperatures
• Mounts using 1/4 inch NPT female threads or surface mount through base
• Visible control point scale with external adjustment screw for easy setting
• Totally enclosed micro switch with snap-acting operation

This direct replacement aquastat features an adjustable set point and functions as a high limit control for hydronic heating systems. The liquid-filled sensing element provides accurate temperature monitoring, while the diaphragm-actuated snap switch breaks power to the burner primary control when the set point is reached. Compatible with immersion wells for safe, accurate temperature sensing in indirect water heaters.
